Can I just check that you have driven an F430 around Suzuka?
If not then you make some rather bold statements about how the car should be driven, particularly for someone who right at the start of this thread said this......
.....as you have just done exactly the same thing.
I also wonder exactly what video you were watching, as the one I've just looked at had plenty of part throttle moments in it, and for good measure a lot of left-foot braking.
The driver is back to full throttle very quickly (as you should do on track and yes I do have experience of that), but its done smoothly. Quite frankly that's a well driven lap in anyone's books.
Now GT5

is far from perfect (not sim is perfect) and it does have its issues, but I would say that you need to give that lap a go in GT5

before decrying that lap as the driver used a good degree of throttle and brake control through corners 1 and 2 to avoid lift-off oversteer.
